[Future of medical lasers].

Whatever the medical field of application of lasers, their future is linked to research and to the realization of systems of automatization which will allow the development of "smart lasers". It will be linked to the improvement of imaging techniques and of medical computers, as well as to the development of new feedback systems; the wavelength and the laser beam dosimetry could then be automatically chosen depending on the aimed tissue and on the biophysical effect desired on the target (coagulation, vaporization, cutting, hyperthermia, photo-ablation). Practically, the future of lasers also depends on the elaboration of new peripheric systems and a better conception of new laser equipment. At last, clinical evaluation of such new surgical technologies with well adapted procedures, formation and information through specific teaching courses and seminars will help to the development of all new laser-technologies.
